Application filed November 9. 1907- Serial No. 401.877.

in its broadest scope has for its mostparticular and essential object to provide-a device of this character, by which the front wheels of the tender will follow the rear wheels of an engine, and the rear'wheels of the tender will vided with a plurality follow the front-wheels of the engine, as W'lll be hereinafter readily manifest.

The invention aims as a further object to provide guiding rods, the, forward ends of which being connected to the axle of the forward wheels of an engine, while the rear ends of said rods are connected to an oscillating'bar of the running gear, which have rod connec-' tions withthe stub axles of the rear wheels of the running gear; the oscillating bar is proof apertures so as to allow the rods connecting the stub axles to be interchanged,'so as to regulate and equalize the oscillatory movement of said stub axles, correlative with the forward wheels of the running gear and the wheels of an engine, as will be clearly evident.

The invention aims. as a further object to provide a flexible frame, for the connection of the forward wheels of the running gear with and a still further 0bdwells in a new and carried by the rear of the rear of an engine, ject of the invention novel coupling device, the running drawn may econnected, for instance a thresher; this coupling device is operated by a suitable rod which is pivotally connected to a lever upon the platform of an engine,

-' (not shown), as. will be readily understood.

This invention com rises further objects and combinations of e ements which will be hereinafterrnore fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

Thefeatures and elements and arrangement thereof, for accomplishing the several objects of the invention, may be changed and varied, that is'to say, in a practical applicaear, to which an object to be tion of the apparatus, with an understanding that the changes and variations accruing from said application are limited to the scope of the appended claims.

To obtain a full and correct understanding ofthe details of construction, combinations. of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accom anying drawings in connection therewith, w erein Figure 1 is a perspective .view of the running gear embodying the principal features of the invention. Fig. 2 .is a top plan view of the running gear, illustrating the different positions of the several arts of the apparatus, with relation to th axles. Fig. 3 is a sectional view on hne 3 3. of Fig. 2, clearly illustrating the construction of the coupling device. Fig. 4 is aers ective view of the flexible frame carrie by tiie forward portion of the running gear. Fig. 5 is a front elevation of the forward portion of the running gear, showing the flexible frame removed, and clearly illustrating the pivotal connection between the tender and the running gear. Fig. 6 is a sectional view taken through low extension 8 and a portion of the stub axle 9.

' Like reference characters are utilized toindicatethe different features and elements of the invention, throughout the several views of the drawings.

In regard to the accom whereinlike reference 0 anying drawings, aracters indicate corresponding parts in the several illustra-I 1 designates the reach .of the shown.

e' oscillatory stub members 3, 4 and 5, the hol-, l

Between the intermediate member.

and the upper member and at their outer ends,

spacing blocks 6 are fixed,through which a pivot bolts or rods 7 extend. These pivot bolts or rods also extend through hollow extensions 8, carried by the oscil 9, so as to form a pivot for said stub axles;

atory stub axles the lower ends of the said pivot bolts or rods have bearings in the lower member 4'ofthe said rear axle, as clearly illustrated in the drawings. The said stub axlesare with wheels 10, as clearly shown in ig. 2;

h rovlded I I is provided with a axle, as clearly whieh projections upon which the bars 30 and the angularlyd1s- 1 terminates into a which is )ivotally mounted between lugs 16,

fixed to t e intermediate member of the rear shown in Fig. 1. Connected to the other arm of the bell crank lever is a rod 17, which, in practice, is adapted to be connected to a lever, (not shown), upon the platform of an engine, (not shown), as will be readily understood. By operating the lever, carpied by the engine, (not shown), the pin 13 is raised or lowered, to disconnect or connect,/the same, to a coupling link of an object to be drawn, (not shown), as will be clearly observed.

Piv ted approximately at the center ofthe reach 1 is an oscillatory bar 18, the outer ends of which are pivotally connected to bars 19, which are in turn pivoted to the said stub axles, as at 20. The said oscillatory bar 18 is provided with a plurality of apertures 21, so as to interchange the pivotal connections of the bars 19, so as to regulate and equalize the oscillatory movement of the said stub axles, correlative with the forward wheels of the running gear and the wheels of the engine.

. he forward axle of the apparatus comrises an upper and lower member 22 and 23, lietween the outer ends of which the forward oscillatory stub axles are pivoted, upon which the forward wheels are mounted, as clearly shown. The said. stub axles are provided with hollow upwardly projecting members 24 through which. the pivot bolts or rods 25 extend, as clearly shown in Figs. 2 and 5. The forward end of the reach is provided with a clamping plate 26, between which and the said reach the lower member. 23 of the forward axle is-pivoted, by means of the bolt 27 as clearly shown in'Figs. 1 and 5. Pivoted to the upper member 22 of the forward axle is a clip 28, com rising ears 29 and 30, between which the bolster 31 is pivoted, which bolster is fixed to the tender 32, shown in Fig. 1 by the dotted lines.

The oscillatory bar 18 has pivoted thereto a pair of bars or rods 33, which are pivotally connected to the forward oscillatory axles, as at 34., as clearly shown in Figs. 1 and 2. Also pivoted to the oscillatory bar 1.8 are a as clearly pair of rods 35, of considerable len th, which I are adapted to be connected to t e axle of the forward wheels of an engine, (not shown), as will be clearly evident.

The lower member 23 of the forward axle extending forwardly of the running gear, in

37, a shaft 38 is ournaled,

fwhat is claimed as plurality of projections,

os ed bars 40 are ivoted loosely, so. as to al-.

tween which ears 43 the bars 39 and 40' are pivoted, as clearly shown; the ivotal con- ,nections between the ears and t e said bars 39 and 40 are of such a the member 41 to have ment, as will be clearly observed.

Pivoted upon the shaft 38 and between the angularly disposed bars is a bar '45, one end of which is pivoted between the ears 44 of the member 41, so as to also allow the member 41 to have a slight movement, as will be clearly seen upon an inspection of the drawings. From the foregoing, the essential features,

character as to allow elements and the operation of the device, to

gether .with the simplicity thereof, will be clearly apparent. I
